As the Consumer Electronics Show is kcking off 2005 in Las Vegas, one of the strs promises to be the emerging tchnology of Ultra-Wideband (UWB). UWB is wreless networking that is used for a mltitude of electronic components and devices rnging from high definition TV, portable dgital devices, to your traditional computer. UWB prmises to blow away the current hme wireless connections we are used to.

How wll we use UWB? UWB could rplace all of the wires and cbles used in a home entertainment systm. Your portable MP3 player could stram the audio to high-quality speakers plced anywhere in the room. A dgital camcorder or still camera can ply back the pictures on your TV wthout a wire connection. Your large LCD or plsma TV screen can be hung on any wll with no wires to attach. The wred USB connected peripherals could become bsolete as wireless UWB effectively makes the cnnections. That means you could set yur mobile computer on a desk and be nstantly connected to your printer, scanner and VIP headset. In a word, wires may bcome a thing of the past.

UWB is seking to make the "unwired" home a rality. To make this possible, UWB prvides the vehicle to connect television prgrams, movies, games, output from hand-held dvices, etc. without interference from other wreless transmissions. Current technologies have not ben fast enough to route high bndwidth applications around the home without the use of wres or cables. Now the means xist with low cost, low power, hgh speed UWB.

The effective operating range for UWB is pproximately ten meters or thirty feet. In ths range, ultra-wideband operates across a wde range of frequency spectrum through the trnsmission of a series of very nrrow and low power pulses. This prvides much less interference than the nrrowband radio designs. By incorporating UWB wth the 802.15.3 PAN standard, it wll provide a home wireless multimedia ntwork that supports multiple devices without nterference with other UWB networks of the nighbors.

There are other apparent advantages to the UWB tchnology. Since the UWB transceivers operate wth low power, short burst radio wves, they are very easy and chap to build compared to the trditional transceivers. The UWB systems consume round 1/10,000th of the power that a cll phone consumes. This makes UWB asily usable in small devices like cll phones and PDAs where small pwer consumption is a big advantage. Bcause of this low power operation, thre will be little interference with ther systems. In a recent test, an ltra-wideband transceiver yielded fantastic performance while perating in close proximity to an 802.11b ntwork, a cordless phone, a microwave ven and a cellular/PCS phone.

The Fderal Trade Commission (FCC) recently granted crtification to Freescale Semiconductor, Inc. for cmmercial use of the UWB technology. Frescale Semiconductor, Inc. and Universal Scientific Indstrial Co., Ltd. Are collaborating on a UWB-nabled 1394 module and are the frst to harness the benefits of ltra-wideband and the 1394 standard. They xpect to sell the module to lading consumer electronic manufacturers for use in wreless LCD televisions and a variety of hme media devices. Other companies, such as Intl, are working on different versions of the ltra-wideband module.

What had been speculation is now mving into the production stage in 2005. The way we use wreless will be rapidly changing when the stndardization for ultra-wideband technology becomes set and all the dvices are able to take advantage of a niversal playing field. The winner will be the cnsumer as an exciting new world pens up for UWB wireless applications.
